CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 610,056dated August 30, 1898.

Application filed December 14, 1897- Serial No. 661,882. (No model.) *l

T0 @ZZ whom, t may concern: Y

Be it known that I, ELIsHA JOHN HUNT, of New York city, in the county and State of New York, have invented a new and Improved Oar-.Axle BOX, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved car-axle box arranged to reduce friction to a minimum and to prevent the car journals and bearings from becoming hot.

The invention consists of novel features and parts and combinations of the same, as will be hereinafter more fully described,and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding `parts in all the figures.

Figure lis a side elevation of the improvement as applied and with parts in section. Fig. 2 is an enlarged transverse section of the improvement on the line 2 2 of Fig. 1. Fig. 3 is an inverted sectional plan view of the same on the line 3 3 of Fig. l, and Fig. 4t is a transverse section of a modified form of the improvement.

On the journal A of the car-axle A is secured a gear-wheel B, in mesh with one or more larger gear-wheels O, journaled on a shaft D, formed in a ball-head D', engaged at the top by a correspondingly-shaped seat or rest formed in the under side of a brass E, fitted to slide in suitable bearings in a box F,

held in the usual pedestal G, secured to theV truck, the box being pressed on by the usual equalizingbar H.

As shown in Fig. 2, two wheels O are employed on the'ends of the shaft D, the head D being between the two wheels but as illustrated in Fig. 4 a single wheel C is in mesh with a wheel B' on the journal A2, and the wheel O has its shaft D? formed at the ends with heads D3, each engaged by a brass E', heldin a box F2, pressed on by an equalizingbar II and fitted in a pedestal G.

It is evident that when the car is in motion the journal A in revolving carries along its gear-wheel B, which on account of being in mesh with the gear-wheels O rotates the latM ter, the said wheels C rolling off on the gear- The forward or outer end of the journal A is also mounted in a brass J, held in a bearn ing K, bolted or otherwise fastened to the box F, the front of which is closedby a suitable door F'to prevent dust or other impurities from passing to the working parts in the said box.

The gearing composed of the wheels B and C is preferably shaped as'shown, with the teeth of the gear-wheels rounded sufficiently to prevent any and all binding. j

By having a ball-joint connection between the shaft D and the brass E it is evident that any twisting strain incident to the car passing around curves and the like will not aect the proper working of the gear-wheels B and O, 'so that no undue friction is encountered between the brass E and the head D, as the latter can turn in the seat of the brass.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. A car-axle box comprising a box proper, a brass in the said box, a journal extending into the said box below the brass, a wheel secured on the said journal and a second wheel having its under side in mesh with the top of the said journal-wheel, the shaft of this second wheel being journaled on the said brass,

substantially as shown and described.

2. A car-axle box, comprising a box proper,

a brass in the said box, a journal extending into the said box, a toothed wheel secured on the said journal, a second toothed wheel having its under side in mesh with the upper-part of the said j ournal-wheel, a shaft carrying the said second toothed wheel and a ball-head on the said shaft and engaging a corresponding seat on the said brass, substantially as shown and described.
